If you compile this way, you have to think of building your java
program as if you were building a C or C++ program.  So when you
compile a given class, you must also compile all the dependencies of
that class, and link them all together.

The traditional way to do this is to compile each .java file to a
separate .o, then link all the .o files together to make your
executable.
